Technical Field

Background

The shortage of fossil fuels and concern over environmental impact has forced society to seek alternative energy sources with less environmental impact, such as renewable energy sources and sustainable energy sources. Consequently, many marine countries are interested in marine energy sources, particularly wave energy. To fully utilize wave energy before development, reliable quantification of wave energy potential is needed. Countless wave forces are evaluated, including global and regional studies, such as coastal waters in the united states, coastal waters in latin america and europe, coastal waters in china, western coast bay of france, red sea on the southwestern coast of the black sea, thailand, indonesia and philippines. The theoretical wave power is estimated to be 2.11 TeraWatt (95% confidence) on a global scale, with a buffer line up to 30 nautical miles, and it is estimated that the total theoretical wave power for the coastal region of the U.S. is approximately 2640 Tera Watt hours/year, roughly equivalent to 65% of the annual U.S. power consumption.

In recent years, china has developed various ocean energy studies. Among them, the exploitation and utilization of wave energy are the most socially concerned issues.

Viability, etc. remain the bottleneck for the development of wave energy technology.

However, the observed data is limited to a specific region and lacks representativeness. Wave simulation has been increasingly studied with the further development of wave theory and numerical techniques. For example, the SWAN model and the WAVEWATCH-1I model are adopted to estimate the overall space-time distribution of wave energy resources in offshore areas of China. Lin et al (2019) wave energy in the neighborhoods of china was evaluated based on 20 years of SWAN post-test. Zheng et al (2011) and Shi et al (2017) performed statistical analysis of the distribution of coastal wave energy in china using re-annual analysis.
